Problem 34PE

A submarine is stranded on the bottom of the ocean with its hatch 25.0 m below the surface. Calculate the force needed to open the hatch from the inside, given it is circular and 0.450 m in diameter. Air pressure inside the submarine is 1.00 atm.

Solution

Step 1 of 3

We need to calculate the force needed to open the hatch from inside of the submarine which is stranded on the bottom of the ocean.

Area of the hatch

The diameter of the circular hatch is

So the radius,

So the area of hatch
